IMPROVEMENT `IN AUTQMATIC GATES..

".-ih'e Schedule referred to in these Letters Patent and making part ofthe same -To all whom timmy conce/rn:

Be it known tliatI,` MICHAEL OREWILER, of Bncyrus, in the county ofGrawiord and State, of Ohio, useful VGrate for Railroads, `purposes and'I do hereby declare is` afull, clear, and exact .description thereof,sufficient toenable 'those skilled in the art to which. iny inventionappertains to make .and use the same, reference-being had to theaccompanying drawing making part of this s'pecieation, in which Farms,and other as applied to a railroad-track. i,

Figure 2 is an end view, showing the position of `Figure 3is atransverse. section, taken in tli'e line-`l The nature of my inventionconsists iii se. conof' a railroad-tran, wagon, or otherl vehicle, willcause the gate to slideopen horizontally, and remain open` gate will beclosedby means of springsj The gate `may be long `enough ,to extendentirely across the gateeway, if desired;` but-I prefer to divide twohalves otthegatewvill slide in opposite directions.: c i i' The top railA is about twice as long as the others, portion passes through a``mortise in a post, C, placed at asiiit-able distance from the gate-Vgate being supported` by the gate-posts B, which sired.l 4

To the outer, end of the' top rail A is pivoted one neeted with a lever,E, which is curved downward to a point just below the bottom of thetrack, and then turned at a right angle,"ian`d rigidly attached to avshaft, Eplaeedparallel with the rails It, and having its bearings in theties fl, upon which the rails rest.`

Projecting outward from the shaft F, at suitable distances apart, areshort levers, I, which aie connected by pivots to the lower ends of rodsJ, the upper ends ot' which are attached to a rail, K, running parallelwiththe rails R for a suitable distance on each side of the gate-way.`

Under the rail K, at suitable distances, and in any desired number, aresprings, S, which i'est upon the ties CP, and serve to keep. the partsin the position shown in fig. 2, They inaybe spiral metallic springs,

or made of rubber or other material, and of any suitable forni.

When the gate is divided in the middle', it ishot' course, necessary toprovide each half of' the gate with the pitman D, lever E, shaft F, andrail K, and theii appendages.

This gate may be applied to farms, tnrnpikes, and other common roads bysubstituting a close' platform for the rails K.

When a. railroadtrain approaches the gate, 4the 'anges of the wheelspress d own the rails K, as shown i'n.` dotted lines 'n'i'g. 3, thus,`by Atheiroonnection throughthe rods J and levers I, giving a partialrevo'i'ut-ion to the shaft F, andthrowing the leverE outward, whichcauses the gate to slide open horizontally,

and remain open until` nthe .rail'K'is relieved of the weight of thetrain, when the springs S press the rail K upward, reversing the formermotion, and closing the gate. l

y,The operation is the same whena'wagon or siinilai' vehicle passesyovei platform substituted for the rail K.

What I claim as new, and desire to secure by Letters Patent, is A Y Thecombination ot' the pitiuan D, bent lever E, shaft F, levers I, rods J,rail K, and springs S, when arranged andv operating as shown anddescribed,

MICHAEL OREWILER.'
